Hierarch Kekropus:
It should be either Emperor Helios or his wife Queen Ramona controlling the Superion.
Ramona was a grand wizard and scholar. When she became queen, she became Helios' right hand, and gained greater powers.
It's obvious from the fact that Helios trusted Ramona with controlling the Superion. However, by taking out Ramona, we may be able to control Superion. Please go and bring Ramona down.
Remember, you cannot go after Ramona alone. You must join forces with many comrades.
